Why GTT’s NO96 Max quietly shapes the future of LNG carriers

Deep inside a modern LNG carrier, the NO96 Max membrane containment system from GTT turns raw steel hulls into shimmering, angular tanks that must not fail when waves slam and temperatures plunge far below freezing. It is deliberately invisible - and absolutely mission critical.

What NO96 Max is built to do

NO96 Max is a membrane LNG containment system designed to keep liquefied natural gas at around minus 163 degrees Celsius inside ships and large storage tanks with controlled boil-off and robust safety margins.

The system uses thin metallic membranes supported by layers of insulation and load-bearing materials, so the cargo never directly touches the ship’s hull yet the structure still follows the hull’s movements in heavy seas.

How it evolves a proven design

GTT positions NO96 Max as an evolution of its long-running NO96 technology family, aiming for lower daily boil-off rates while keeping the geometry and construction processes familiar to shipyards and classification societies.

For builders and owners, that mix of incremental efficiency gain and continuity in design can be attractive, because it limits retraining needs and simplifies approvals while promising better lifetime operating economics.

Everyday operation on board

For the crew, the NO96 Max system is mostly something they hear and monitor rather than touch: valve sounds, sensor readouts, temperature graphs and boil-off gas flow feeds into the vessel’s fuel and reliquefaction systems.

When insulation and membrane do their job, the bridge sees predictable tank pressures and gas availability, which makes slow steaming or flexible routing decisions less nerve-wracking on long transits between liquefaction plants and import terminals.

Where it aims to stand out

Compared with older containment technologies, NO96 Max is intended to cut LNG losses and improve usable cargo volume, which over a ship’s 20 to 30-year life can translate into meaningful revenue differences for fleet operators.

The system also tries to balance thermal efficiency with maintainability, so planned inspections, repairs and partial renewals can be carried out within standard dry-docking windows rather than forcing prolonged off-hire periods.

Risks, limits and what investors should watch

Despite its strengths, NO96 Max ultimately competes with alternative containment concepts and with changing energy flows: if LNG demand or regulatory frameworks shift faster than expected, order books for new carriers could soften.

Net-net, NO96 Max is a technically sophisticated product central to GTT’s business model, but its long-term commercial success depends heavily on shipbuilding cycles, charter rates and global energy transition policies.

Company context and stock angle

GTT, headquartered in France, earns royalties and engineering fees when shipyards and terminal operators adopt systems like NO96 Max in newbuilds and storage projects worldwide. As of recent trading days, shares of Gaztransport & Technigaz SA (FR0011726835) are listed on Euronext Paris in euros.
